“I had the chairman of Ferrari down here for the board meeting last week and he had a chance to look at the car, and he was speechless,” Marchionne said in an interview with Detroit radio WJR-AM. “I mean, for Ferrari to admit that the car is a unique vehicle is a hell of a compliment to the work that’s gone on here. So I’m delighted. I mean, so far, knock on wood, we’re doing well.”

Ferrari and Chrysler are both owned by parent company Fiat and Marchionne is di Montezemolo’s boss.

Refresher: Power for the 2013 SRT Viper comes from an all-aluminum, mid-engine 8.4-liter V10 that makes 640 horsepower and 600 lb-ft of torque. The engine is mated to a Tremec TR6060 6-speed manual transmission with a shorter throw shifter, closer gear ratios and a final drive ratio that has been shortened to 3.55 from 3.07.
